tant? dimmi New We ttmt NATHAN CARR, JR., AND JOHN CARR, OF MNll/IOUTH, ILLINOIS. c v Letters Patent No. 85,509, dated January 5, 1869. i

The Schedule referred to in these Letters Patent and making part of the same ToA all 'whom )it may concern Be it known that we, NATHAN GARR, Jr., and JOHN GARR, of the city of Monmouth, county of Warren, and State of Illinois, have invented certain new and useful Improvements in Cultivators; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a portion of this specication, in which- Figure 1 is a perspective view of our invention.

Figure 2 is a bottom or' under-side view.

Similar letters of. reference indicate corresponding 'parts in both figures.

The nature of this; invention relates to a joint for cornecting the beams of cultivators to the inain frame an The invention consists of the different parts being so formed and arranged as to admit of adjusting the distance of the plows apart, and their height from the ground, or depth of running; also, allowing free vertical andlateral movement ofthe plows, at the same time holding them rm against a wabbljng or unsteady motion. v A To enable others to understand the construction and operation of our invention, we Cwill proceed to describe it with reference to the drawings.

A represents a semicircular casting, attached to' the main frame C, of the cultivator, by pivot-bolt K and bolt L, in the vertical arm, extending from forward side of said casting C.

B represents the coupling-spindle, which is supported or held between the ends of the semicircular part of Y casting A.

d represents the end of an ordinary beam, and

E represents a top-beam plate, 'with a circular enlargement at the forward end, and concave on the uuder side, except a small flat part, j, next the periphery, which acts as a bearing on the spindle B. This plate E is secured to the beam by bolts a a.

M represents a cylindrical bearingplate, passing through ahole in the plaie E, and forming the journal, on which lateral movement of the plows is obtained.

F represents the head of cylinder M.

P andR represent 4transverse slots in the lower end of cylinder M; the slots l forming the bearing on the spindle B, on which the vertical movement of the plows is obtained, the extended sides of p lateE at the same time resting on the spindle B, forming a perfect support and preventive against wabbling or unsteady movement ot' the plows.

The slots R, in cylinder M, allow the hook S to embrace the spindle B, and the shank of hook. S passes up through the cylinder M, and is provided with nut H, by which the whole device is held together and regulated.

T represents a wrench, with a flat hook, V, fitting the spindle B, and it may be placed on the spindle, at either sideof plate E, for the purpose of adjusting the distance of the plows apart.

The whole device being pivoted at K, admits of lowering or raising the points-of the beams by changing the bolt through holes L L L.

Having thus describedv our invention,

What We claim as new, and desire to secure by Let- The plate E, cylinder M, and hook S, with rnut H,

`constructed and arranged as described, and combined.

ner substantially as described, and for the purpose set forth.
